GAS-ENGINE STARTER.

To all whom t may concern Be it known that I, STEPHEN S. KRAYER, a citizen of the United States, residing at the city of St. Louis, State of Missouri, have invented a new and vuseful Gras-Engine Starter, of which the following is a specification.

This invention relates to gas engine starters and more particularly to a valve or distributing device for starters, which is interposed between the fuel oil .supply and the several cylinders of an engine.

An object of the invention is to provide a simple' and durable device of the character mentioned whereby a predetermined quantity of oil may be mixed with air and which carbureted air, by a simple manipulation of the valve, may be directly introduced into the cylinders of an engine, in proper sequence, under sufficient pressure to put the gas under compression in the cylinders. After which it may be ignited by usual means, effectively to start the operation of the engine.

With this and other obvious ends in view I have designed, combined and arranged the several coperating parts, comprising my present invention, in the manner hereinafter described and illustrated in the drawings, in which- Figure 1 is a section through the valve case and the valve plug carrying the oil chambers, showing the several coperating pipe connections. Fig. 2 is a vertical section through the device, showing one of the oil chambers in a position to inject a charge of carbureted air into a cylinder. Fig. 3 is a semi-diagrammatic view comprising a vertical section of the case with the valve plug removed, the valve plug, and an end elevation ofthe valve case viewing certain 0f the gas outlet passages in elevation, a part of said case being broken away to show the gas outlet openings through the valve case, the passage of the air and gas being indicated by the distinctive lines. Fig. 4 is a fragmentary vertical sect-ion of the valve case with the valve plug removed, showing the oil inlet passage and the distributing grooves in the case. Fig. 5 is a vertical section through the valve case and valve plug, a portion of the valve plug being broken away so as to more clearly illustrate the oil inlet passages for the oil leading to the several oil chambers. Figi is a view ofl specification of Lettersratent. Applicationled August 30, 1912. Serial No.

the same parts as are disclosed in Fig. 5 viewed from the opposite side of the case, disclosing the oil outletpassages. is a horizontal section of a fragment of the device illustrating the' oill inlet passages, and a detail of one end of the oil chambers carried by the valve plug. Fig. 8 is a frag# mentary horizontal section of the valve plug, showing the outlet end of one ofthe oil chambers carriedtherein, and Fig; 9 is a fragmentary view illustrating the' outlet end of one of the 'oil chambers carried by the valvev plug. f

In theembodiment of my invention, illus-v trateduinthe drawings', 1 indicates thecasing which is provided with a tapering valve seat 2 and with a removable cover 3. ,The

cover 3 is provided threaded hollow boss 4 stem of the valve plug 5 projects. In-order to effect aA tight closure, packing material 6 is placed around the stem ofthe valve plug andan exteriorly threaded nut'7 is screwed with an interior-ly through which the into the threaded boss 4. A removablev handle 8 surmounts the stem. of thefvalve plugl 5 whereby the same may be manipulate Fig. 7

The valve case has a passage 9 through the wall thereof, saidpassage constituting an oil inlet. The passage .9 is

tapped at its outer end to receive a threaded oil supply pipel 10. Diametrically opposite to the said inlet passage 9 is an outlet passage 11 which is likewise threadedl at itsA outer opening to receive the threaded oil outlet pipe 12. At the side of the valve case intermediate the oil inlet and outlet pass sages is a :third passage 13 tappedto'receive a threaded air inlet pipe 14. The said a-ir inlet passage has an L-shaped branch passage 15v leading therefrom to the interior Through the wall 1 of the valve case, opposite to the air inlet passages, are formed a plurality of gas outlet ypassages 16. The arrangement of the outlet passagesA is such that certain thereof are in the same plane` as the upper branch of the air inlet and certain of them in the same' plane as the lower branch ofthe air inlet; said passages being arranged infstaggered relationship. as clearly illustrated in Fig. 1 of the drawings. vRadiating from the inner opening of the oil inlet passage 9 are chan'- nels or grooves 17 formed in the interior surface ofthe valve case. .At theopposite si e, communicating with theiiiterir opend V110` l so " as shown at 2O in ing of the oil outlet passageis a second series of grooves or channels 18. rlhe arrangement of the oil inlet passage and the oil outlet passage with their respective communicating grooves or channels 17 and 18, is such that oil entering the inlet passage will be distributed by means of the grooves or channels 17 to the oil chambers carried by the valve plug, hrough which it ilows and is discharged into the grooves or channels 18, from thence it flows to the outlet passage 11, when the valve plug is in normal adjustment, as shown in full lines in Fig. 1 of the drawings.

The oil chambers 19, that are carried by the valve plug, comprise a series of openings or bores extending through the valve plug and are so arranged that when the valve plug is seated in its valve sea-t that certain ones of said chambers will be in the same plane as the upper branch of the air inlet and certain ones will be in the same plane with the lower branch of the air inlet. The oil inlet ends of the chambers are restricted Fig. 7 and the opposite ends of said chambers are threaded as shown at 21. The inlet openings of the oil chambers are arranged in a rectangular series and the chambers pass obliquely through the valve plug so that the outlet ends thereof constitute a staggered series of openings arranged as shown in Fig. 6 of the drawings. Each of the chambers 19 is provided with a removable threaded plug 22 which has a passage 23 therethrough. In assembling the parts of the device a quantity of wire gauze 24C is bent and packed into the several chambers 19 and the plugs or caps 22 are then inserted to close the chambers and to keep the gauze in place, the oil passing through the passages Q3. Each of the plugs or caps 22 is provided with' a transverse groove Q5 to receive a screw-driver or suitabley instrument for adjusting the same within the threaded ends of the chambers. It is apparent that the capacity of each oil chamber may be varied by manipulation of the plug or cap 22. The purpose of the gauze 2li, within the chambers 19, is to permit the oil to be more readily mixed and vaporized when the air from supply pipe passes therethrough.

l prefer to place the device in a vertical position such as 1s shown in Fig. y1. The oil enters through the supply pipe 10 and the i passage 9 and flows by gravity, by. way oi the grooves 17, into thence through the grooves or'channels 1S to the outlet passage 11 and thence to the outlet pipe 12.` the inlet passage 9 should be placed on a lower level than the oil tank from which oil is supplied tothe pipe 10, so that the oil when the valve is in normal adjustment will continuously flow through the several pasthe several chambers 19 l lt will be understood that sages into the outlet pipe 12, which may be connected with the usual carburetor. Thus it will be seen that the oil chambers are always charged with oil, When it is desired to inject gas into the cylinders of the engine the valve plug 5 is manipulated by the handle S so that the oil chambers will be brought into registration at one end with the air supply passage, and at the other end with the respective gas outlet passage. The air which is supplied through the pipe ll is under suliicient pressure to vaporize the oil in the oil chambers and to force the carbureted air or gas into the gas outlet passages, thence it is conducted to the respective cylinder of the engine with which the specific outlet pipe 26 communicates. The passage of the air from the supply pipe 1li, through the oil chambers to the gas outlet passages will be clearly understood by reference to Fig. 3, which view illustrates in detail the manner in which the several ports register as the valve plug is operated. It will be noted by reference to Fig. 1 that all the passages may be closed by bringing the valve plug to a neutral position by turning the handle 8 one eighth of a turn from the position shown in dotted lines in this figure of the drawings. lt will, ot course, be understood that as soon as the handle is moved from the normal position shown in Fig. 1, the oil inlet and outlet pasages will be closed.
